Key Features & Specifications
- Non-Sparking Safety: Made from high-grade aluminum bronze (CuAl10Fe3), this tool generates no sparks upon impact, eliminating ignition risks in flammable atmospheres (e.g., oil refineries, gas plants, paint shops).
- Double Open End Design: Two precisely machined openings (16mm and 18mm) for versatile fastening and loosening of bolts and nuts, saving time on the job.
- Explosion-Proof Construction: The material is inherently non-ferrous and anti-magnetic, meeting the highest safety standards for zone 0/1/2 explosive environments.
- Corrosion Resistance: Aluminum bronze offers excellent resistance to salt water, chemicals, and humidity – ideal for offshore and refinery applications.
- Durable & Long-Lasting: With a hardness of HB 110–130 and tensile strength ≥ 450 MPa, the wrench withstands heavy use without deforming or cracking.
- Ergonomic Handle: Smooth rounded edges and a comfortable grip reduce hand fatigue during extended operation.
- Customizable Options: Available in other sizes (6mm–80mm), special coatings, or with insulated handles upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between aluminum bronze and beryllium copper non-sparking tools?
A: Both are non-sparking, but aluminum bronze (CuAl10Fe3) is more cost-effective, harder, and offers better corrosion resistance. Beryllium copper is slightly stronger but more expensive. Our aluminum bronze wrenches provide excellent performance for most explosive environments. -
Q: Is this wrench suitable for use in wet or underwater conditions?
A: Yes, aluminum bronze exhibits excellent resistance to saltwater and many chemicals, making it ideal for offshore or humid refinery areas. However, avoid prolonged immersion in strong acids or alkalis without proper coating. -
Q: Can I get this wrench in other sizes or with a different opening angle?
A: Absolutely. We offer custom sizes from 6mm to 80mm and can adjust the head angle (15°, 30°, 45°) upon request. Minimum order quantity may apply for custom specs. -
Q: How do I verify the non-sparking property of the tool?
A: Each tool is tested with a standard spark test (grinding against steel at high speed) before leaving our factory. No sparks are produced. We also provide a material certificate on request. -
Q: What is the typical lead time for this 16x18mm wrench?
A: For standard sizes, we carry stock and can ship within 7–15 days after payment. Custom orders may take 20–30 days depending on quantity and specifications. -
Q: Do you offer private labeling or custom packaging?
A: Yes. We can print your company logo on the tool (laser engraving) and provide custom blister cards, boxes, or polybags. Please discuss with our sales team. -
Q: How should I maintain this wrench to prolong its life?
A: After use, wipe clean with a dry cloth. Avoid abrasive cleaners. Store in a dry place. No oiling is required – the natural oxide layer protects the surface. -
Q: Can I use this wrench on stainless steel fasteners without causing galling?
A: Aluminum bronze is softer than steel, so it reduces the risk of galling on stainless steel threads. However, use reasonable torque to prevent deformation of the wrench jaws.
